Application filed February 23, 1883. (No model.)

Y To ActZZ whom t may concern: n

Be it known that we, LUKE R. HITCHCOCK and JOHN W. LUFKIN, citizens ofthe United States, residing at Four Mile, in the countyr of Oattaraugus and State of New York, have invented certain new and useful improvements in Sncker-Rod Extractors for Oil. and other Wells; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the' art to which it appertains to make and use the same.

Our invention relates to certain new and useful improvements in extractors for raising or removing suckerrods from oil, salt, or other Wells when they have parted or broken, leaving a portion ofthe sucker-rods in the tubing in the well, often causing great delay in raising it, Vand in some cases requiring the with drawal of the tubing, thereby incurring eX- pense and the risk of dropping the tool in the tubing Vin the wel] and the invention consists in novel features of construction and combination of parts, all as will be hereinafter fully described, and set forth in the claims hereto annexed.

Referring to the accompanying drawings, Figures 1 and 2 are views in perspective ol' a spear provi ded, respectively, with a pivoted or spring catch; Figs. 3 and 4, views in perspective, respectively, of the shell and section ol" sucker-rod; Fig. 5, vertical section of the sev' eral parts of the sucker-rod extractor when connected together. y

In the drawings, A represents the spear, having a pivoted catch, a, or .i spring-catch, b, near its lower end, and a socket, B, at its upper end, provided with an. interior screwthread, by which it is connected to a section of sucker-rod O, having screw-threaded ends c c'.

D represents a metallic shell or shield for the spear A, which has a longitudinal slot, d, and a`bent lange, d', at its upper end, against which the socket B of the spear rests. lThe slot Z permits of the shell or shield being contracted or expanded, and with the spear A' completely surrounds the sucker-rod, thereby preventing any parts of the rod, loose rivets, or straps from coming in contact with the tubing as the shield or shellhaving the spear is drawn through it. The spear is rigidly secured iu the shell or shield, and both the shell or shield and spear held firmly in position by the screw-threaded end C ci the section O,

and the flange c'z of said section O pressing `55 back, and when raising the shell or shield the catch presses into or toward the wood or iron of the sucker-rod, takes a firm hold, and draws it ont. The whole 'l'orms a combined shell or spear held firmly together bythe seeti on O of the sucker-rod, and as the shell or shield is 7o drawn out ofthe tubing `it will keep the suckerrod (being removed) pressed against the catch and prevent it slipping ofi", and cannot be removed from the shell or shield until the section C is unscrewed. Then it comes out readily 7 5 without resorting to means that might destroy the spear.

We are aware that a tool-extractor or drillrod grab consisting ol' a tube-section provided with a catch is old, and such we do not wish 8o to be understood as claiming, broadly, as ol" our invention.

The slotted shell or shield should be made as large as possible so as to just enter the tubing ofthe well, and so that the shell or shield will spring inwardly when coming in eontart with dentations or any roughened snrlaee on the interior of the tubing, and thereby pass rendily by them.

We are aware that a slotted shield or shell 9o having a catch connected to its interior snrface is old, and such we do not wish to bc nnderstood as claiming as ol" our invention.

Having thus fully described our invention,

what we claim as new, and desire to seenre by Letters Patent, ism

1. The combination, with the spear A, having the pivotedor spring ealeh, ofthe slotted shell or shield D, and the section (l l'or securing the spear and shell or shield together, subloo stantially as and for the purpose herein shown and described.
